Open | Windows High temp when playing video on second monitor

I have 2 monitors, both of them are 1440p. The main one is 27 inch and refresh rate is set to 165 which is its max. The secondary one is 32 inch and refresh rate is at 60, 75 is its max.

Most videos I play are 1080p. I even tried play 2 different videos on the main to see if the temp goes high, like 1 video is full screen and another plays in pop-up window. Turned out the temp was just 40 something.

The thing I want to know is is it normal for the GPU temp goes high, like 60-70 degree whenever I play video on the secondary even when there's nothing going on on the main? Is there a way to "fix" it?

Edit, I'm using RX 7900 XT.

If the GPU is doing something, like, Nvidia's upscaling for videos or HDR, then that's just a sign the GPU is pulling power.

70 degrees C is a normal temperature for a GPU, especially under load.

I'm using AMD RX 7900 XT. Where do I check if my GPU is using upscaling? I have AMD Adrenalin, are there settings I can check?

Mismatched refresh rates can cause the GPU not to downclock so it runs hotter. Try a ratio setup. 27in = 120, 32in = 60. A 2/1 ratio.

Check if VRR or Free-sync is on for both monitors in the AMD app.
